| 2 | Dark matter direct search sensitivity of the PandaX-4T experiment显示文摘The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2 at a dark matter mass of 40 Ge V/c^2. | HongGuang Zhang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui BinBin Dong DeQing Fang ChangBo Fu Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo ZhiFan Guo Ke Han ChangDa He ShengMing He Di Huang XingTao Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju ShaoLi Li Yao Li Heng Lin HuaXuan Liu JiangLai Liu YuGang Ma YaJun Mao KaiXiang Ni JinHua Ning XiangXiang Ren Fang Shi AnDi Tan AnQing Wang Cheng Wang HongWei Wang Meng Wang QiuHong Wang SiGuang Wang XiuLi Wang XuMing Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu JuMin Yuan JianFeng Yue Dan Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，3： | 6 |
| 3 | Rotation Angle Control Strategy for Telescopic Flexible Manipulator Based on a Combination of Fuzzy Adjustment and RBF Neural Network显示文摘The length of fexible manipulators with a telescopic arm alters during movement.The dynamic parameters of telescopic fexible manipulators exhibit signifcant time-varying characteristics owing to variations in length.With an increase in the manipulators’length,the nonlinear terms caused by fexibility in the manipulators’dynamic equations cannot be ignored.The time-varying characteristics and nonlinear terms of telescopic fexible manipulators cause fuctuations in rotation angles,which afect the operation accuracy of end-efectors.In this study,a control strategy based on a combination of fuzzy adjustment and an RBF neural network is utilized to improve the control accuracy of fexible telescopic manipulators.First,the dynamic equation of the manipulators is established using the assumed mode method and Lagrange’s principle,and the infuence of nonlinear terms is analyzed.Subsequently,a combined control strategy is proposed to suppress the fuctuation of the rotation angle in telescopic fexible manipulators.The variation ranges of the feedforward PD controller parameters are determined by the pole placement strategy and length of the manipulators.Fuzzy rules are utilized to adjust the controller parameters in real-time.The RBF neural network is utilized to identify and compensate the uncertain part of the dynamic model of the fexible manipulators.The uncertain part comprises time-varying parameters and nonlinear terms.Finally,numerical simulations and prototype experiments prove the efectiveness of the combined control strategy.The results prove that the proposed control strategy has a smaller standard deviation of errors.Therefore,the combined control strategy is more suitable for telescopic fexible manipulators,which can efectively improve the control accuracy of rotation angles. | Dongyang Shang Xiaopeng Li Meng Yin Fanjie Li Bangchun Wen | 2022 | Chinese Journal of Mechanical Engineering2022，35，4： | 4 |
| 4 | A CRISPR/Cas12a-empowered surface plasmon resonance platform for rapid and specific diagnosis of the Omicron variant of SARS-CoV-2显示文摘The outbreak of the COVID-19 pandemic was partially due to the challenge of identifying asymptomatic and presymptomatic carriers of the virus,and thus highlights a strong motivation for diagnostics with high sensitivity that can be rapidly deployed.On the other hand,several concerning SARS-CoV-2 variants,including Omicron,are required to be identified as soon as the samples are identified as‘positive’.Unfortunately,a traditional PCR test does not allow their specific identification.Herein,for the first time,we have developed MOPCS(Methodologies of Photonic CRISPR Sensing),which combines an optical sensing technology-surface plasmon resonance(SPR)with the‘gene scissors’clustered regularly interspaced short palindromic repeat(CRISPR)technique to achieve both high sensitivity and specificity when it comes to measurement of viral variants.MOPCS is a low-cost,CRISPR/Cas12a-systemempowered SPR gene-detecting platform that can analyze viral RNA,without the need for amplification,within 38 min from sample input to results output,and achieve a limit of detection of 15 fM.MOPCS achieves a highly sensitive analysis of SARS-CoV-2,and mutations appear in variants B.1.617.2(Delta),B.1.1.529(Omicron)and BA.1(a subtype of Omicron).This platform was also used to analyze some recently collected patient samples from a local outbreak in China,identified by the Centers for Disease Control and Prevention.This innovative CRISPR-empowered SPR platform will further contribute to the fast,sensitive and accurate detection of target nucleic acid sequences with single-base mutations. | Zhi Chen Jingfeng Li Tianzhong Li Taojian Fan Changle Meng Chaozhou Li Jianlong Kang Luxiao Chai Yabin Hao Yuxuan Tang Omar AAl-Hartomy Swelm Wageh Abdullah GAl-Sehemi Zhiguang Luo Jiangtian Yu Yonghong Shao Defa Li Shuai Feng William J.Liu Yaqing He Xiaopeng Ma Zhongjian Xie Han Zhang | 2022 | National Science Review2022，9，8： | 3 |
| 5 | Differentiation of coral trout (Plectropomus leopardus) based on an analysis of morphology and complete mitochondrial DNA: Are cryptic species present?显示文摘Two morphotypes of Plectropomus leopardus have been identified; morphometric and meristic analyses show that there is no diagnostic difference between them. A difference in color pattern was the most appropriate phenotypic character with which to distinguish between the two morphotypes. Complete mitochondrial DNA sequencing, however, indicated a clear difference between the two morphotypes. Barcoding analysis revealed no significant difference (P>0.05) in CO1 or ND2 divergence among intramorphotypic individuals, even between geographically separated populations, whereas the intermorphotypic CO1 and ND2 divergences were large enough (averaging 0.95% for CO1 and 1.37% for ND2) to clearly discriminate between the two morphotypes. The color pattern difference, geographical distribution, together with the mtDNA and barcode sequencing data, suggest that the two morphotypes should be of two subspecies or even two species. | CAI Xiaopeng QU Meng DING Shaoxiong WANG Hangjun WANG Hongjie HU Luyi SU Yongquan | 2013 | Acta Oceanologica Sinica2013，32，6： | 2 |

| 10 | Novel thioxanthone host material with thermally activated delayed fluorescence for reduced efficiency roll-off of phosphorescent OLEDs显示文摘2,7-Di(9,9-dimethyl-9 H-fluoren-1-yl)-9 H-thioxanthen-9-one(DMBFTX) with thermally activated delayed fluorescence(TADF) was well designed and synthesized. The phosphorescent organic lightemitting device(PHOLED) based on this novel TADF host material displays a stable red phosphorescence region, a peak external quantum efficiency(EQE) value of 12.9% and a low EQE roll-off of 38.8% at a luminance of 10000 cd/m^2, which is benefited from the reverse intersystem crossing(RISC) of TADF host and less populated triplet exitons. Notably, the red device based on the TADF host DMBFTX exhibits superior electroluminescence performance and reduced efficiency roll-off compared with the one hosted by commercially available host 1,3-bis(9-carbazolyl)benzene(mCP), illustrating the high potential of employing the TADF host material with small energy gap to reduce efficiency roll-off in PHOLED. | Hui Wang Xiaopeng Lv Lingqiang Meng Xiaofang Wei Ying Wang Pengfei Wang | 2018 | Chinese Chemical Letters2018，29，3： | 1 |

| 12 | An improved evaluation of the neutron background in the PandaX-Ⅱ experiment显示文摘In dark matter direct detection experiments,neutron is a serious source of background,which can mimic the dark matter-nucleus scattering signals.In this paper,we present an improved evaluation of the neutron background in the PandaX-II dark matter experiment by a novel approach.Instead of fully relying on the Monte Carlo simulation,the overall neutron background is determined from the neutron-induced high energy signals in the data.In addition,the probability of producing a dark-matter-like background per neutron is evaluated with a complete Monte Carlo generator,where the correlated emission of neutron(s)andγ(s)in the(α,n)reactions and spontaneous fissions is taken into consideration.With this method,the neutron backgrounds in the Run 9(26-ton-day)and Run 10(28-ton-day)data sets of PandaX-II are estimated to be(0.66±0.24)and(0.47±0.25)events,respectively. | QiuHong Wang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui YingJie Fan DeQing Fang ChangBo Fu LiSheng Geng Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo Ke Han ChangDa He Di Huang Yan Huang YanLin Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju YiHui Lai Kun Liang HuaXuan Liu JiangLai Liu WenBo Ma YuGang Ma YaJun Mao Yue Meng Parinya Namwongsa KaiXiang Ni JinHua Ning XuYang Ning XiangXiang Ren ChangSong Shang Lin Si AnDi Tan AnQing Wang HongWei Wang Meng Wang SiGuang Wang XiuLi Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu Jumin Yuan Dan Zhang HongGuang Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，3： | 0 |
| 13 | Constraining self-interacting dark matter with the full dataset of PandaX-II显示文摘Self-interacting dark matter(SIDM)is a leading candidate proposed to solve discrepancies between predictions of the prevailing cold dark matter theory and observations of galaxies.Many SIDM models predict the existence of a light force carrier that mediates strong dark matter self-interactions.If the mediator couples to the standard model particles,it could produce characteristic signals in dark matter direct detection experiments.We report searches for signals of SIDM models with a light mediator using the full dataset of the PandaX-II experiment,basing on a total exposure of 132 tonne-days.No significant excess over background is found,and our likelihood analysis leads to a strong upper limit on the dark matter-nucleon coupling strength.We further combine the PandaX-II constraints and those from observations of the light element abundances in the early universe,and show that direct detection and cosmological probes can provide complementary constraints on dark matter models with a light mediator. | Jijun Yang Abdusalam Abdukerim Wei Chen Xun Chen Yunhua Chen Chen Cheng Xiangyi Cui Yingjie Fan Deqing Fang Changbo Fu Mengting Fu Lisheng Geng Karl Giboni Linhui Gu Xuyuan Guo Ke Han Changda He Shengming He Di Huang Yan Huang Ran Huo Yanlin Huang Zhou Huang Xiangdong Ji Yonglin Ju Shuaijie Li Qing Lin Huaxuan Liu Jianglai Liu Xiaoying Lu Wenbo Ma Yugang Ma Yajun Mao Yue Meng Nasir Shaheed Kaixiang Ni Jinhua Ning Xuyang Ning Xiangxiang Ren Changsong Shang Guofang Shen Lin Si Andi Tan Anqing Wang Hongwei Wang Meng Wang QiuHong Wang Siguang Wang Wei Wang Xiuli Wang Zhou Wang Mengmeng Wu Shiyong Wu Weihao Wu Jingkai Xia Mengjiao Xiao Xiang Xiao Pengwei Xie Binbin Yan Yong Yang Chunxu Yu Hai-Bo Yu Jumin Yuan Ying Yuan Xinning Zeng Dan Zhang Tao Zhang Li Zhao Qibin Zheng Jifang Zhou Ning Zhou Xiaopeng Zhou | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，11： | 0 |
| 14 | Alternatingly stacked thin film electrodes-based compact aqueous hybrid electrochemical capacitors for hundred-volts AC line filtering显示文摘Filtering capacitor with compact configuration and a wide range of operating voltage has been attracting increasing attention for the smooth conversion of the electric signal in modern circuits.Lossless integration of capacitor units can be regarded as one of the efficient ways to achieve a wider voltage range,which has not yet been fully conquered due to the lack of rational designs of the electrode structure and integration technology.This study presents an alternatingly stacked assemble technology to conveniently fabricate compact aqueous hybrid integrated filtering capacitors on a large scale,in which a unit consists of rGO/MXene composite film as a negative electrode and PEDOT:PSS based film as a positive electrode.Benefiting from the synergistic effect of rGO and MXene components,and morphological characteristics of PEDOT:PSS,the capacitor unit exhibits outstanding AC line filtering with a large areal specific energy density of 1,015 μF V^(2)cm^(-2)(0.28 μW h cm^(-2)) at 120 Hz.After rational integration,the assembled capacitors present compact/lightweight configuration and lossless frequency response,as reflected by almost constant resistor-capacitor time constant of 0.2 ms and dissipation factor of 15% at120 Hz,identical to those of the single capacitor unit.Apart from standing alone steadily on a flower,a small volume(only 8.1 cm^(3)) of the integrated capacitor with 70 units connected in series achieves hundred-volts alternating current line filtering,which is superior to most reported filtering capacitors with sandwich configuration.This study provides insight into the fabrication and application of compact/ultralight filtering capacitors with lossless frequency response,and a wide range of operating voltage. | Lixia Wang Lingyu Zhao Meirong Song Lixia Xie Xiaopeng Wang Xin Li Yanjie Huang Min Wei Qiu Jin Xianglong Meng Yang Zhao | 2023 | Journal of Energy Chemistry2023，，3： | 0 |

| 17 | Protective Effects of Sepia Ink Melanin on Hepatic Tissue in Streptozotocin-Induced Diabetic Mice显示文摘Diabetes mellitus(DM)has emerged as a serious public health concern,due to the high morbidity and mortality resulted from its complications,such as diabetic nephropathy,diabetic cardiovascular complication,and diabetic neuropathy,etc.In this study,we investigated the beneficial effects of sepia ink melanin(SIM)on hyperglycaemia and the restoration of diabetic symptoms in streptozotocin(STZ)-induced diabetic model mice.At first,the normal experimental mice were performed with intraperitoneal injection of STZ(40 mg(kg BW)^(−1))(BW,body weight)to attain diabetes and then were treated with different concentrations of SIM(120,240 and 480 mg(kg BW)^(−1))for four weeks.After treatment,significant decrease in gluconeogenesis were determined,accompanied by a notable increase in both glycolysis and oxidative enzyme activities in SIM-treated groups,such as liver marker enzymes in the serum and key antioxidant enzymes in liver.qPCR results revealed the transcriptional alterations in SIM-treated groups.SIM exposure increased the expression levels of several genes related to insulin transduction and PI3K/Akt pathway,including PI3K,Akt,Irs-2,and InsR.Meanwhile,expression levels of Dicarbonyl/l-xylulose reductase(Dcxr)and UDP-glucose dehydrogenase(Ugdh),which are in-volved in pentose-glucuronate interconversion pathway,were also elevated in SIM-treated groups.Furthermore,histological observation results indicated that nuclear deformation and organelle dissolution were improved,thus could enhance the liver function.These results demonstrated that SIM can be effective in ameliorating diabetic symptoms and improving disease management for diabetic patients. | WANG Xiaopeng HAN Meng DONG Hui ZHAO Yun SONG Weiwei WANG Chunlin MU Changkao LI Ronghua | 2022 | Journal of Ocean University of China2022，21，5： | 0 |
| 18 | Statistical learning based facial animation显示文摘To synthesize real-time and realistic facial animation, we present an effective algorithm which combines image- and geometry-based methods for facial animation simulation. Considering the numerous motion units in the expression coding system, we present a novel simplified motion unit based on the basic facial expression, and construct the corresponding basic action for a head model. As image features are difficult to obtain using the performance driven method, we develop an automatic image feature recognition method based on statistical learning, and an expression image semi-automatic labeling method with rotation invariant face detection, which can improve the accuracy and efficiency of expression feature identification and training. After facial animation redirection, each basic action weight needs to be computed and mapped automatically. We apply the blend shape method to construct and train the corresponding expression database according to each basic action, and adopt the least squares method to compute the corresponding control parameters for facial animation. Moreover, there is a pre-integration of diffuse light distribution and specular light distribution based on the physical method, to improve the plausibility and efficiency of facial rendering. Our work provides a simplification of the facial motion unit, an optimization of the statistical training process and recognition process for facial animation, solves the expression parameters, and simulates the subsurface scattering effect in real time. Experimental results indicate that our method is effective and efficient, and suitable for computer animation and interactive applications. | Shibiao XU Guanghui MA Weiliang MENG Xiaopeng ZHANG | 2013 | Journal of Zhejiang University-Science C(Computers and Electronics)2013，14，7： | 0 |
| 19 | Analyzing surface sampling patterns using the localized pair correlation function显示文摘Point distributions with different characteristics have a crucial influence on graphics applications. Various analysis tools have been developed in recent years, mainly for blue noise sampling in Euclidean domains. In this paper, we present a new method to analyze the properties of general sampling patterns that are distributed on mesh surfaces. The core idea is to generalize to surfaces the pair correlation function(PCF) which has successfully been employed in sampling pattern analysis and synthesis in 2D and 3D. Experimental results demonstrate that the proposed approach can reveal correlations of point sets generated by a wide range of sampling algorithms. An acceleration technique is also suggested to improve the performance of the PCF. | Weize Quan Jianwei Guo Dong-Ming Yan Weiliang Meng Xiaopeng Zhang | 2016 | Computational Visual Media2016，2，3： | 0 |
| 20 | Fabrication of Tungsten Carbide Nanoparticles from Refluxing Derived Precursor显示文摘Tungsten carbide(WC) nanoparticles were fabricated from a novel refluxing-derived precursor. The precursor was prepared by acid hydrolysis of Na2WO4 with concentrated HCl in water followed by refl uxing with ethanol and n-Dedocane, respectively. Then it was heat-treated to 1 200 ℃ for 2 h in vacuum to obtain WC nanoparticles. X-ray studies reveal the formation of hexagonal tungsten carbide and the grain size of 24.3 nm. SEM image shows WC nanoparticles with particle size of 20-60 nm. Long time refl uxing results in alkane dehydrogenation and coke formation. The coke is the carbon source in the carbothermal reduction reaction. The novel route of two-stage refl uxing is quite general and can be applied in the synthesis of similar carbides. | 文季秋 LI Yongdi MENG Xiaopeng YIN Guangfu 姚亚东 | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，2： | 0 |
